7 Claims.

This invention relates to the art of nailing or stapling by means of portable machines, particularly machines of the type which are carried to the work to be nailed, as distinguished from nailing machines of the type wherein the work to be operated upon is brought to the machine.

Nailing or stapling machines of the type with which the present invention is concerned gen-' erally consist of a magazine for receiving a stick or stack of nails, and a reciprocable plunger which is actuated by a blow imparted thereto by a hammer (or pneumatically) to drive the first nail of the stack into the object, the succeeding nails being then advanced progressively as each nail is driven home. Nailing machines of the above type generally include a flat base which is adapt-- ed to be placed upon the object to be nailed, and the nail is then driven at right angles to the base to enter the object to be nailed in a direction at right angles to that surface of the object upon which the nailing machine is brought to rest. It frequently happens that it is desirable to drive a nail at a fixed angle (other than a right angle) to the surface of the object being nailed, or at a fixed inclination to the surface supporting and taking the thrust of the nailing machine. It is one of the objects of the present invention to provide means applicable to nailing machines of the type that drive the nail at right angles to the machine-supporting surface and which will adapt the machine for driving nails at a fixed angle other than a right angle to said surface. In view of the fact that the nailing machine always projects its nail in a direction at right angles to the base of the machine, it is obvious that if a nail is to be driven at an inclination to the nail-receiving surface, then the base of the nailing machine must be held at a corresponding angle to said surface. It is a further object of the present invention to provide means for positively holding the nailing machine at any desired fixed angle to the surface where the nail is to be driven.

In accordance with one embodiment of the present invention the objects above set forth are attained by providing two similar templates which are releasably but rigidly secured one on each side of the nailing machine. The templates project below the base on opposite sides of the machine and have work-engaging surfaces at the desired angle to the base of the machine. In view of the fact that the templates are on opposite sides of the machine they will hold the machine against skewing or tilting in a. direction sideways of the machine. The templates extend substantially be low the base of the machine and en age the work sideways direction. As a result of the use of the two templates of the present invention the machine can be brought into engagement with a corner where nailing operations are to be performed and held to drive the nails into the corner at fixed predetermined angles. Different templates may be provided for holding the nailing machine in dilierent fixed angular inclinations to the work.

It is a further object of the present invention to provide templates that can be readily made from scrap pieces of wood Which are generally. available in places where nailing operations are to be performed. As a result the owner of a nailing machine may quickly form templates to suit a particulariob and quickly and easily secure such templates to a machine, and may readily change the templates when a change is necessary,

In nailing machines the construction is general-' 1y such that when a nail is driven home to its ultimate position the head of the nail is at a fixed distance from the base of the machine. Where a template is to be made by the owner of a machine for fixing the angle of inclination of the machine it is important that that template shall not alter the spacing of the nail-ejecting opening in the machine from the work. If the template should increase the distance of the nailejecting opening of the' machine from the work the nail will not be driven into the work a sufficient distance. Conversely, if the template were to decrease the distance from the nail-ejecting opening to the work then the nail would be driven too far into the work. It is one of the objects of the present invention to provide an arrangement of one or more templates on a nailing machine wherein the thickness of the template or templates has no bearing whatsoever on the amount of space between the nail-ejecting opening on the machine and the work. As a result, if the template is made under inaccurate conditions, such as might prevail in the shop of the user of the machine, variations in template thickness will not alfect the nailing action. The templates merely fix the angle of inclination of the ma chine with respect to the work.

The attainment of the above and further objects of the present invention will be apparent from the following specification taken in conjunction with the accompanying drawing forming a part thereof.

In the drawingf Figure .1 is a side view of a nailing machine embodying a pair of templates of the present invention, said machine being shown in the position in which it is used;

Figure 2 is a bottom view of the nailing machine, said view being taken along the line 2-2 of Figure 1; and

Figure 3 is. a front view of the nailingv machine.

Reference may newbie had more particularly to the drawing. A nailing machine is indicated in general by the reference numeral I. This machine may be of any desired construction, the preferred construction being one such as shown. in my pending application Serial. No. 512,673., filed December 1, 1943, to which reference may be had for a more complete description. The. machine comprises two similar castings 2 and 3 secured together in face to" face relationship; The bottoms of the castings 2 and 3 are per-- fectly fiat. At the forward end of the machine each casting 2 and 3 has an enlarged head I0 which is an integral" part of the casting. The handle part- II extends from the head to the base of the casting, and provides means for gripping the machine. A rectangular driving plunger it having a driving head I6- is reciprocable in the head [0 in a direction at right angles to the base. The plunger drives the nails one at atime upon each downward movement of the plunger. Each nail is driven below the bottom plates of the machine into thewood to be nailed in place,

which constitutesthe work. To that effect the two castings of the nailing machine have at the base thereof aligned openings which constitute a nail-ejection opening IOI, all as shown and described in my above identified application.

The nails are drivenin a direction at right angles't'o the base I02 of'the machine. Ordinarily the base I02 of the machine rests upon the object being nailed'so that the nails are being drivenat, right angles to" the surface upon which the nailing machine rests. At times it is necessary to drive a nail in such a direction or at suchan inclination that because of the shape of the work it is not possible to position the mailing machine with its base I02 resting onthe work in a plane at right angles to the desired direction of drive of the nail. This is illustrated, for instance, inthe case of a frame of a window or showcase wherein the frame portion I05 is adapted to hold a glass pane I00, the pane beingheld in place by an angle or corner strip I01 of wood which rests on a ledge F00 on the frame part I05. The nail [09 is to be driven at an angle such as is indicated in Figure 1-. There is only a limitedamount of permissible leeway in the angle of inclination of the nail. If the nail is driven at an angledeviating too much in one direction from the position shown, then it" is liable to strike the glass with resulting damage. If the inclination deviates too much in the opposite direction then the nail is liable to cause cracking of the front exposed surface of the frame I 05.

In accordance with the present invention means is provided for holding the nailingmachine I at the proper angle of inclination with respect to the frame I05 so that the nail will be driven inthe proper direction. To that effect there are provided two templates II '0--I ll] of identical shape which act as guide members or adapters for facilitating such action. Each template con' sists of a fiat wooden board cut to the desired shape. The two templates embraces the opposite sides 5 l2--I I2 of the machine and are bolted in place by bolts II3--I I3 that extend through holes in the two templates and thro gh correface I02 enters the work at the proper angle of inclination. At its front surface I20 each template terminates flush with the corresponding front. surface of the nailing machine or may terminate at any point rearwardly thereof. Adja- 3 cent. the front of each template the template is cut out along a line l2| which coincides with or is above the base plane I02 of the nailin machine so that the template in no way increases the vertical spacing of the nailing machine from the curved surface I22 of thecorner I01 that is being nailedin place.

Asmay be seenfrom Figures 2 and 3, the templates I l-0---I'I 0 are on opposite sides ofthe nailing' machine and thus hold the nailing machine against tilting sideways, that is, in a direction in the plane of the paper asseen in Figure 2'. Also, it is to be noted that the surface N5 of each template extends an appreciable distance below the surface I02 of the nailing machine. This holdsthe nailing machine against tilting in either direction in the plane of the paper as seen in Figure I- It is thus apparent that because of these two templates it is very simple for an operator to hold the nailing'machine against the work I05 at the'proper angle, as illustratedin Figure 1', and then by imparting a hammer blow against the head it to drive a nail I 09 intothe work at exactly the proper angle. For different types of Work: or for different corner constructions different templates may be used: wherein the sur-- face N5 of the template is at a different angle to the base i02'. Likewise, that surface of the template which engages the work may be either above or below the surface I02, depending upon the nature of the work. For instance, if a corner [01" is to. be nailed to a floor at the base of the floor where a vertical wall rises from the floor, then the surface H5 of the template would be projected upwardly rather than downwardly, to engage thevertical wall corresponding to the wall I06, rather than to engage the wall I I6.

In compliance with the requirements of the patent statutes I have here shown and described a preferred embodiment of my invention. It is, however, to be. understood that the invention is not limited to the precise construction here shown, the same being merely illustrative of the principles of the invention.
